Why Choose the ABB 1SDA054744R1 T4 W FP 3p VR Fixed Part?
The ABB 1SDA054744R1 is a three-pole fixed part for a withdrawable Tmax T4 circuit breaker, designed as part of the ABB Tmax low-voltage moulded-case circuit-breaker system. Identified as T4 W FP 3p VR, this fixed-part assembly provides the stationary interface required for installing a compatible withdrawable T4 circuit breaker in industrial and commercial power distribution equipment.
The fixed part remains installed within the switchboard while the compatible withdrawable circuit breaker can be removed for inspection, servicing or replacement. This arrangement helps simplify maintenance and enables the breaker to be withdrawn without removing the permanent fixed-part assembly from the electrical installation.
Featuring a three-pole configuration and rear flat vertical terminals, the 1SDA054744R1 is rated for operational voltages up to 690 V AC and 750 V DC. Its compact fixed-part construction is designed specifically for compatible ABB Tmax T4 withdrawable circuit-breaker installations.
